This factory service and repair manual for the 1986 Chevrolet W7500 Tiltmaster has a wide gap between its two engines. Both are turbocharged diesel sixes, but one displaces 8.4 liters and 513 cubic inches while the other measures 5.8 liters and 353, and almost nothing in their specifications transfers between them. The manual keeps the two apart accordingly, then brings the truck back together in the chassis sections for the low tilt straight truck body built as W7R042.

Known issues on the 1986 W7500 Tiltmaster. The federal record carries no recall for this year and no complaint from an owner, so the useful thing to describe is the coverage itself. Each of the two diesels is given its own procedures, clearances, injection values and torque figures, because a specification that suits the 513-cubic-inch engine is wrong for the 353. Everything common to the truck — frame, driveline, brakes, steering and the cab and chassis wiring — is documented once, with diagrams and diagnostics that apply to both builds.
